CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims the benefit of priority fromChinese Patent Application No. 2021112343731, filed on 22 Oct. 2021, theentirety of which is incorporated by reference herein.

TECHNICAL FIELD

The disclosure relates to the technical field of atomization devices, inparticular to an atomization assembly and an electronic atomizer.

BACKGROUND

Atomization devices on the market, especially electronic cigarettes,have some problems. For example, in order to meet the needs of users,some electronic cigarettes contain more e-liquid inside, but theseelectronic cigarettes are difficult to achieve a better anti-leakageperformance in the case of being filled with more e-liquid. Electroniccigarettes will have a “grumbling” sound during the inhalation process,which will affect the user’s inhalation experience. In addition, anelectronic cigarette is usually only suitable for a few types ofe-liquids, resulting in poor applicability of the electronic cigarette.

SUMMARY

The disclosure aims to solve at least one of the technical problems inthe existing technology. To this end, the disclosure provides anatomization assembly that has both a larger e-liquid storage capacityand better e-liquid anti-leakage performance. The atomization assemblycan reduce noise generated in the use process of the user, and hasbetter applicability.

The disclosure further provides an electronic atomizer with theabove-mentioned atomization assembly.

An atomization assembly according to an embodiment in the first aspectof the disclosure includes: a first housing, having a flue pipe in whicha smoke outlet passage is arranged; a base, which is connected to thefirst housing to form an accommodating cavity inside the first housing,the flue pipe being located in the accommodating cavity; a separator,which is arranged in the accommodating cavity to separate theaccommodating cavity into a first e-liquid storage cavity and a seconde-liquid storage cavity, where the first e-liquid storage cavity isconfigured to store e-liquid, the separator has at least one e-liquidpassage hole which is communicated with the first e-liquid storagecavity and the second e-liquid storage cavity and a first air passageformed inside the separator; an e-liquid storage cotton, which isarranged in the second e-liquid storage cavity and capable of adsorbinge-liquid; and an atomization core, where the e-liquid storage cotton isin contact with a periphery of the atomization core, the atomizationcore has a second air passage inside, the second air passage and thesmoke outlet passage are respectively communicated with the first airpassage, and the atomization core is capable of heating the e-liquid togenerate smoke which is allowed to enter the second air passage.

The atomization assembly according to this embodiment of the disclosureat least has the following beneficial effects.

According to the atomization assembly provided by the disclosure, a partof the e-liquid is stored in the e-liquid storage cotton, and theremaining part of the e-liquid is stored in the first storage cavity.Therefore, compared to direct injection of all e-liquid into one cavity,the atomization assembly of the disclosure can reduce the amount ofe-liquid with higher fluidity in the atomization assembly, and reducethe pressure of the e-liquid, thereby reducing the risk of e-liquidleakage of the atomization assembly (including a risk of leakage intothe passage through which the smoke flows, and a risk of leakage to theoutside of the base). The e-liquid storage cotton itself has a certainvolume. For the same cavity, the e-liquid storage capacity in the cavitywith an e-liquid storage cotton is less than that without an e-liquidstorage cotton. Compared to the storage of all the e-liquid in thee-liquid storage cotton, the atomization assembly of the disclosure onlystores a part of the e-liquid in the e-liquid storage cotton, and thuscan store more e-liquid. Therefore, the atomization assembly of thedisclosure has both a larger e-liquid storage capacity and bettere-liquid anti-leakage performance.

Due to the e-liquid storage cotton, the pressure of the e-liquid nearthe atomization core is relatively low, such that an e-liquid intakerate of the atomization core will not be too large, and the e-liquid ina liquid state will not easily penetrate into the second air passage ofthe atomization core. In this way, droplets in a flue can be reduced,and the sound of “grumbling” generated when air flows through thedroplets can be reduced, thereby reducing the noise that the user hearsin the use process of the atomization assembly.

In addition, by providing the atomization assembly with the e-liquidstorage cotton, the applicability of the atomization assembly can beimproved. Different types of e-liquids have different viscosities. Inthe case that the power of the atomization core is constant, anatomization rate of the atomization core is basically unchanged, butrates (that is, an e-liquid intake rate of the atomization core) ofe-liquids of different viscosities entering the atomization core aredifferent. Generally, it is usually necessary to make the e-liquidintake rate slightly greater than the atomization rate so as to ensurethe continuity of the user’s inhalation and the taste of the smoke.Therefore, one kind of atomization core is usually only suitable for afew kinds of e-liquids. If the atomization assembly is provided with thee-liquid storage cotton, the difference in the rates of differente-liquids entering the atomization core is relatively small. In the casethat the e-liquid intake rate of the atomization core is slightlygreater than the atomization rate, the atomization assembly isapplicable to more e-liquids, and thus has high applicability.

In some embodiments of the disclosure, the atomization assembly furtherincludes an e-liquid filling plug, where the first housing or the baseis provided with an e-liquid filling hole which is communicated with thefirst e-liquid storage cavity, and the e-liquid filling is configuredfor plugging the e-liquid filling hole.

In some embodiments of the disclosure, the flue pipe is arranged aroundthe first sleeve portion; an outer wall of the first sleeve portion isprovided with a first annular rib which abuts against the inner wall ofthe first housing; and the first annular rib has elasticity.

In some embodiments of the disclosure, the separator further includes asecond sleeve portion which is connected to the separation portion atone side facing the second e-liquid storage cavity, and an inner cavityof the second sleeve portion serves as a portion of the first airpassage; the e-liquid storage cotton is provided with a positioningpassage; and the second sleeve portion and the atomization core are botharranged to pass through the positioning passage.

In some embodiments of the disclosure, the atomization core includes: acore pipe, which is connected to the base and provided with an avoidanceport; a fixed seat, which is connected to a bottom of the core pipe; aheating wire, which is connected to the fixed seat and is accommodatedinside the core pipe; and an e-liquid guide cotton, which is connectedto an inner side of the core pipe, where an inner side of the e-liquidguide cotton serves as a portion of a wall surface of the second airpassage, and the avoidance port is configured to allow at least one ofthe e-liquid guide cotton and the e-liquid storage cotton to passthrough, such that the e-liquid guide cotton is in contact with thee-liquid storage cotton; and the heating wire is connected to thee-liquid guide cotton.

In some embodiments of the disclosure, a sum of an e-liquid storagecapacity of the first e-liquid storage cavity and an e-liquid storagecapacity of the second e-liquid storage cavity is not less than 10 ml.

An electronic atomizer according to an embodiment in a second aspect ofthe disclosure includes the atomization assembly as mentioned above.

Furthermore, the particular feature, structure,material, or characteristic described may be combined in any suitablemanner in any one or more embodiments or examples.

The disclosure provides an atomization assembly. The atomizationassembly includes a first housing 204, a base 218, a separator 205, ane-liquid storage cotton 208, and an atomization core 221. In anelectronic atomizer 101, the atomization assembly may be used inconjunction with a power supply assembly, which can supply power to theatomization assembly, so as to atomize e-liquid in the atomizationassembly.

Referring to FIGS. 2, 3 and 5 , the first housing 204 is hollow and isconnected to the base 218, thereby forming an accommodating cavity 502inside the first housing 204. The first housing 204 has a flue pipe 301which is disposed in the accommodating cavity 502, and the flue pipe 301has a smoke outlet passage 303 inside. The separator 205 is arranged inthe accommodating cavity 502 to separate the accommodating cavity 502into a first e-liquid storage cavity 304 and a second e-liquid storagecavity 501. A space at a side of the separator 205 facing the base 218is the second e-liquid storage cavity 501, and a space at the other sideof the separator 205 facing the flue pipe 301 is the first e-liquidstorage cavity 304. Referring to FIG. 6 , the separator 205 is providedwith an e-liquid passage hole 606, and the first e-liquid storage cavity304 and the second e-liquid storage chamber 501 are both communicatedwith the e-liquid passage hole 606. It should be noted that profilescorresponding to FIGS. 3 and 5 are not cut to the e-liquid passage hole606, so the e-liquid passage hole 606 is not shown in FIGS. 3 and 5 .

In conjunction with FIGS. 3 and 5 , the first e-liquid storage cavity304 and the second e-liquid storage cavity 501 are both configured tostore e-liquid (e-liquid is not shown), but the storage methods areslightly different. The e-liquid storage cotton 208 is arranged in thesecond e-liquid storage cavity 501, the e-liquid located in the firste-liquid storage cavity 304 is directly filled into the first e-liquidstorage cavity 304, and the e-liquid located in the second e-liquidstorage cavity 501 is absorbed into the e-liquid storage cotton 208. Apart of the atomization core 221 is arranged in the second e-liquidstorage cavity 501. The e-liquid storage cotton 208 is in contact withthe atomization core 221. The atomization core 221 can generate heat,such that the e-liquid in the e-liquid storage cotton 208 generatessmoke after being heated. Referring to FIG. 3 , the separator 205 has afirst air passage 305, the atomization core 221 has a second air passage306, and both ends of the first air passage 305 are respectivelycommunicated with the second air passage 306 and the smoke outletpassage 303. If a passage through which smoke flows is referred to as aflue, the flue includes a first air passage 305, a second air passage306, and a smoke outlet passage 303.

The general operating principle of the atomization assembly is asfollows: the e-liquid in the e-liquid storage cotton 208 is heated toproduce smoke, and a pressure difference generated by the user’sinhalation will drive the smoke to flow through the second air passage306, the first air passage 305 and the smoke outlet passage 303 insequence, such that the smoke will eventually flow out of the flue; asthe e-liquid in the e-liquid storage cotton 208 is consumed, thee-liquid in the first e-liquid storage cavity 304 will flow from thee-liquid passage hole 606 to the second e-liquid storage cavity 501, andwill be absorbed by the e-liquid storage cotton 208 in the seconde-liquid storage cavity 501, thereby replenishing the e-liquid to thee-liquid storage cotton 208.

According to the atomization assembly provided by the disclosure, a partof the e-liquid is stored in the e-liquid storage cotton 208, and theremaining part of the e-liquid is stored in the first storage cavity.Therefore, compared to direct injection of all e-liquid into one cavity,the atomization assembly of the disclosure can reduce the amount ofe-liquid with higher fluidity in the atomization assembly, and reducethe pressure of the e-liquid, thereby reducing the risk of e-liquidleakage of the atomization assembly (including a risk of leakage intothe passage through which the smoke flows, and a risk of leakage to theoutside of the base 218). The e-liquid storage cotton 208 itself has acertain volume. For the same cavity, when the e-liquid storage cotton208 is arranged in the cavity, the e-liquid storage capacity in thecavity is less than that in a case where no e-liquid storage cotton 208is arranged in the cavity. Compared to the storage of all the e-liquidin the e-liquid storage cotton 208, the atomization assembly of thedisclosure only stores a part of the e-liquid in the e-liquid storagecotton 208, and thus can store more e-liquid. Therefore, the atomizationassembly of the disclosure has both a larger e-liquid storage capacityand better e-liquid anti-leakage performance.

Due to the e-liquid storage cotton 208, the pressure of the e-liquidnear the atomization core 221 is relatively low, such that an e-liquidintake rate of the atomization core 221 will not be too large, and thee-liquid in a liquid state will not easily penetrate into the second airpassage 306 of the atomization core 221. In this way, droplets in a fluecan be reduced, and the sound of “grumbling” generated when air flowsthrough the droplets can be reduced, thereby reducing the noise that theuser hears in the use process of the atomization assembly.

In addition, by providing the e-liquid storage cotton 208 in theatomization assembly, the applicability of the atomization assembly canbe improved. Different types of e-liquids have different viscosities. Inthe case that the power of the atomization core 221 is constant, anatomization rate of the atomization core 221 is basically unchanged, butrates (that is, an e-liquid intake rate of the atomization core) ofe-liquids of different viscosities entering the atomization core 221 aredifferent. Generally, it is usually necessary to make the e-liquidintake rate slightly greater than the atomization rate so as to ensurethe continuity of the user’s inhalation and the taste of the smoke.Therefore, one kind of atomization core is usually only suitable for afew kinds of e-liquids. If the atomization assembly is provided with thee-liquid storage cotton 208, the difference between the rates ofdifferent e-liquids entering the atomization core 221 is relativelysmall. In the case that the e-liquid intake rate of the atomization core221 is slightly greater than the atomization rate, the atomizationassembly can be applied to more e-liquids, and thus has highapplicability.

According to the atomization assembly of the disclosure, a sum of ane-liquid storage capacity of the first e-liquid storage cavity 304 andan e-liquid storage capacity of the second e-liquid storage cavity 501may be set to be no less than 10 ml, so as to reduce the number of timesthat the user replaces the atomization assembly or re-adds the e-liquid,thereby improving the convenience in use of the atomization assembly. Asmentioned above, since the e-liquid storage cotton 208 is arranged inthe atomization assembly, even if the total amount of the e-liquid isgreater than 10 ml, leakage of e-liquid is not prone to occur in theatomization assembly. It should be noted that the e-liquid storagecapacity of the first e-liquid storage cavity 304 directly depends onthe size of the first e-liquid storage cavity 304, and the e-liquidstorage capacity of the second e-liquid storage cavity 501 mainlydepends on the size of the second e-liquid storage cavity 501 and anadsorption capacity of the e-liquid storage cotton 208 for the e-liquid.

The other structures of the atomization assembly will be described indetail below.

Referring to FIGS. 2 to 4 , in some embodiments, the atomizationassembly further includes a suction nozzle 202 and a main body plug 201.The suction nozzle 202 is connected to an end of the first housing 204,and configured to contact the user’s mouth. The main body plug 201 isconfigured to plug the suction nozzle 202 to avoid a hygienic problemcaused by the falling of dust into the flue when the atomizationassembly is not in use. Referring to FIG. 10 , in some embodiments, thesuction nozzle 202 and the first housing 204 may also be integrated intoone piece.

Referring to FIG. 14 , in some embodiments, the atomization core 221includes a core pipe 211, a fixing ring 212, an e-liquid guide cotton209 and a heating wire 210. The core pipe 211 is installed on the base218. The fixing ring 212 is installed at the bottom of the core pipe211. The fixing ring 212 is connected to the heating wire 210 to fix theposition of the heating wire 210, and a pin of the heating wire 210passes through the fixing ring 212. The e-liquid guide cotton 209 isconnected to an inner wall of the core pipe 211, and an inner surface ofthe e-liquid guide cotton 209 serves as a portion of a wall surface ofthe second air passage 306. The heating wire 210 is connected to thee-liquid guide cotton 209. The heating wire 210 may be directlyconnected to the inner surface of the e-liquid guide cotton 209 so as toreduce the difficulty in connection between the heating wire 210 and thee-liquid guide cotton 209. In other embodiments, it may be considered toinsert the heating wire 210 into the e-liquid guide cotton 209.

Referring to FIG. 14 , a positioning passage 1301 is arranged in thecenter of the e-liquid guide cotton 209, and a part of the core pipe 211may be arranged to pass through the positioning passage 1301. The corepipe 211 is provided with an avoidance port 1401, which allows at leastone of the e-liquid guide cotton 209 and the e-liquid storage cotton 208to pass through, so that the e-liquid guide cotton 209 is in contactwith the e-liquid storage cotton 208. It may be provided that thee-liquid guide cotton 209 penetrates out of the core pipe 211 andcontacts the e-liquid storage cotton 208; or the e-liquid storage cotton208 is squeezed into the core pipe 211 to contact the e-liquid guidecotton 209; or a part of each of the e-liquid guide cotton 209 and thee-liquid storage cotton 208 is squeezed into the avoidance port 1401,and the two parts are in contact with each other. The e-liquid guidecotton 209 can also adsorb the e-liquid. After the e-liquid guide cotton209 comes into contact with the e-liquid storage cotton 208, thee-liquid in the e-liquid storage cotton 208 can be transferred to thee-liquid guide cotton 209. The heating wire will generate heat toatomize the e-liquid in the e-liquid guide cotton 209, and the smokewill then enter the second air passage 306.

Referring to FIG. 2 , in some embodiments, the e-liquid guide cotton 209may be set in a cylindrical shape, and the outer wall of the e-liquidguide cotton 209 is in contact with the inner wall of the e-liquidstorage cotton 208. Referring to FIG. 14 , in some embodiments, adeformation seam 1302 may also be arranged on the e-liquid storagecotton 208. The deformation seam 1302 is communicated with thepositioning passage 1301. A part of the e-liquid guide cotton 209surrounds the outside of the heating wire 210, and the other part of thee-liquid guide cotton 209 penetrates out of the avoidance port 1401 andis arranged in the deformation seam 1302. The part of the e-liquidstorage cotton 208, which serves as the wall surface of the deformationseam 1302, can clamp the e-liquid guide cotton 209. In contrast, themethod shown in FIG. 14 can increase a contact area between the e-liquidstorage cotton 208 and the e-liquid guide cotton 209 and increase ane-liquid intake rate of the atomization core 221.

An e-liquid filling hole 401 may be formed in the first housing 204 orthe base 218 so as to add the e-liquid to the atomization assembly. Thee-liquid filling hole 401 is communicated with the first e-liquidstorage cavity 304, the e-liquid enters the first e-liquid storagecavity 304 from the e-liquid filling hole 401, and a part of thee-liquid will enter the second e-liquid storage cavity 501 through thee-liquid passage hole 606. The atomization assembly further includes ane-liquid filling plug 203, which can plug the e-liquid filling hole 401to prevent e-liquid leakage. The e-liquid filling plug 203 abuts againstthe wall of the e-liquid filling hole 401 to seal the e-liquid fillinghole 401 and to prevent the e-liquid from leaking from the e-liquidfilling hole 401. The e-liquid filling plug 203 may be made of someelastic materials, such as silicone, to improve a sealing effect.

FIG. 4 shows a case where the e-liquid filling hole 401 is formed in thefirst housing 204. Referring to FIGS. 11 to 13 , in some embodiments, alateral portion of the separator 205 is spaced apart from the inner wallof the first housing 204 to form an e-liquid filling passage 1101; thee-liquid filling passage 1101 serves as a portion of the first e-liquidstorage cavity 304; and the e-liquid filling hole 401 is communicatedwith one end of the e-liquid filling passage 1101. This arrangement maybe suitable for cases where the first housing 204 is inconvenient to beprovided with an e-liquid filling hole. For example, in FIG. 10 , thedesign shown in FIG. 4 cannot be adopted since the suction nozzle 202and the first housing 204 are integrated.

In conjunction with FIGS. 11 and 12 , in some embodiments, at least onee-liquid passage hole 606 is formed in the separator 205 at one side(e.g., the right side of the separator 205 in FIG. 12 ) facing thee-liquid filling passage 1101, so as to improve the utilization rate ofthe e-liquid. If the e-liquid filling hole 606 is not arranged in thisside of the separator 205, this part of e-liquid in the e-liquid fillingpassage 1101 will be unlikely to enter the second e-liquid storagecavity 501, that is, this part of the e-liquid will be wasted.

Referring to FIG. 6 , in some embodiments, the separator 205 includes aseparation portion 603 and a first sleeve portion 601. The first sleeveportion 601 is hollow, and an inner cavity inside the first sleeveportion 601 serves as a portion of the first air passage 305. The outeredge of the separation portion 603 abuts against the inner wall of thefirst housing 204. The first e-liquid storage cavity 304 and the seconde-liquid storage cavity 501 are respectively arranged on both sides ofthe separation portion 603. The protruding first sleeve portion 601cooperates with other components in the atomization assemblyconveniently (the flue pipe 301 is arranged around the first sleeveportion 601), thereby positioning the separator 205 in the atomizationassembly.

Referring to FIG. 6 , in some embodiments, the outer wall of the firstsleeve portion 601 is provided with a first annular rib 604, which haselasticity. The first annular rib 604 abuts against the inner wall ofthe smoke outlet passage 303, thereby preventing the e-liquid fromentering the smoke outlet passage 303 from a gap between the flue pipe301 and the first sleeve portion 601 (that is, preventing the e-liquidfrom leaking into the smoke outlet passage 303).

Similarly, in some embodiments, the outer edge of the separation portion603 is provided with a second annular rib 605, which has elasticity. Thesecond annular rib 605 abuts against the inner wall of the first housing204. The second annular rib 605 is configured to prevent the e-liquidfrom flowing into the second e-liquid storage cavity 501 from the gapbetween the separator 205 and the first housing 204. If the e-liquidflows into the second e-liquid storage cavity 501 from the gap betweenthe separator 205 and the first housing 204, the amount of e-liquidentering the second e-liquid storage cavity 501 within the same periodof time will increase, which easily causes the actual e-liquid intakerate of the atomization core 221 to be too large and thus affects thenormal operation of the atomization assembly. The second annular rib 605is arranged mainly to ensure that the atomization assembly can workaccording to a preset working condition.

In some embodiments, the separator 205 may be configured as anintegrally formed silicone part. In other embodiments, a plastic partmay also be formed by injection molding first, where the shape of theplastic part is similar to that of the separator 205 shown in FIG. 6 .However, the plastic part is not provided with the first annular rib 604and the second annular rib 605, but the plastic part is provided withannular grooves at positions corresponding to the first annular rib 604and the second annular rib 605. Then, silicone rings are installed inthese annular grooves, and used as the first ring rib 604 and the secondring rib 605.
